## Abstract

The paper describes a system of notions (a T-model) developed for representing temporal information on the semantics-pragmatics level in a natural language understanding system. The choice of the notions to be considered has been relied upon a necessity of special facilities for describing situations with various de gre e s of detailing according to an inexact character of temporal information in natural language texts. Time is mod e lled as a straight directed line, and four main objects: point, interval, quantity and chain together with four groups of notions associated with them are included into the model. A structure of the T-model and its base notions are briefly outlined in the first section of the paper. The representation of temporal information by means of T-model objects is then considered by examples.
